Description

Technical Field

[0001] The invention belongs to the technical field of oil mist emission and separation, and in particular relates to an oil mist emission and separation device. Background Art

[0002] In industrial production, many industries such as petrochemicals and mechanical processing have oil and gas production links. Based on environmental protection requirements and the safety of equipment operation, it is necessary to effectively discharge and separate the generated oil mist. At present, there are many oil mist emission and separation devices on the market, which can initially treat oil mist to a certain extent.

[0003] However, there are still many problems to be solved in the existing oil mist discharge and separation devices. In terms of oil collection, during the oil and gas separation operation, oil is often stored at the bottom of the oil receiving tank. Due to the flow of the oil body, this part of the stored oil generally does not cause the oil to adhere to the bottom of the tank, but the oil remaining at the high position at the bottom of the oil receiving tank is difficult to remove. Due to the limitations of the design and actual operation of the oil receiving funnel tank, conventional means are difficult to reach the high-level area for treatment, causing this part of the oil to adhere and accumulate for a long time and be difficult to clean.

[0004] From the perspective of equipment maintenance, the existing oil mist discharge tank cannot be cleaned regularly. As the service time increases, impurities in the oil mist continue to accumulate in the tank, which may clog the pipes in the tank, affect the normal operation of the equipment, and reduce the oil mist discharge separation efficiency.

[0005] For the core component of the oil mist discharge separation device, the filter packing, it is difficult to ensure the ventilation state during long-term filtering operation. In actual operation, oil droplets are easy to adhere to the surface of the filter packing. If not handled in time, the oil will gradually accumulate on the filter packing plate, hindering the passage of gas, reducing the filtering effect, and thus affecting the equipment's ability to continuously handle the oil-gas mixture.

[0006] More importantly, when unstable oil and gas enter the oil mist discharge tank, the existing device cannot effectively deal with it. When the oil and gas pressure is unstable, the excessive pressure will continuously and unevenly impact the tank wall of the oil mist discharge tank. Under such harsh working conditions for a long time, the tank wall is prone to fatigue damage, deformation and even rupture, which greatly shortens the service life of the oil mist discharge tank.

[0007] In summary, it is of great practical significance and urgent need to develop an oil mist discharge separation device that can effectively remove residual oil at high positions in the oil receiving funnel tank, achieve regular impurity removal in the oil mist discharge tank, ensure long-term ventilation of the filter packing, and adapt to unstable oil and gas pressure. Summary of the invention

[0008] Purpose of the invention: In view of the deficiencies in the prior art, the present invention provides an oil mist discharge separation device, which solves the problems of the prior oil mist discharge separation device, such as the difficulty in removing high oil at the bottom of the oil collecting funnel tank during oil collection, the inability to regularly remove impurities from the oil mist discharge tank, the difficulty in ensuring the long-term ventilation state of the filter packing, and the inability to effectively cope with the unstable oil and gas pressure shock that causes the tank wall to be easily damaged.

[0009] An oil mist discharge and separation device comprises a climbing platform and an oil mist discharge tank, a notch is arranged on the climbing platform, an exhaust pipe is arranged on the top of the oil mist discharge tank, an air intake pipe is arranged on the side of the oil mist discharge tank, and a support leg is arranged on the bottom of the oil mist discharge tank, and the device is characterized in that an oil receiving funnel tank is arranged inside the oil mist discharge tank, a rubber ring is sleeved on the oil receiving funnel tank, a telescopic pipe is arranged inside the oil receiving funnel tank, a rubber sleeve is arranged on the telescopic pipe, and friction lines are arranged on the rubber sleeve, a porous oil outlet plate is arranged between the bottom of the telescopic pipe and the oil receiving funnel tank, the oil receiving funnel tank is fitted with the inner wall of the oil mist discharge tank, and the oil receiving funnel tank is The telescopic tube moves with the movement, and a spring is sleeved on the telescopic tube extending out of the oil receiving funnel tank. A limit plate is arranged on the top of the telescopic tube, and the spring is limited by the limit plate. A spring groove is arranged on the top of the oil mist discharge tank, and the bottom of the spring is limited by the spring groove. A rotating disk is arranged on the top of the limit plate. A filter packing disk mechanism is arranged inside the oil mist discharge tank, and the filter packing disk mechanism vibrates when the telescopic tube moves, thereby ensuring that oil droplets can quickly drip from the filter packing disk mechanism and that gas can be discharged from the filter packing disk mechanism. The air inlet pipe is arranged between the filter packing disk mechanism and the oil receiving funnel tank.

[0010] The filter packing disc mechanism includes a packing ring, two springs and strip spring pieces. The packing ring is connected to the top of the oil mist discharge tank through a group of two springs. The telescopic tube passes through the packing ring and slides in the packing ring. A group of strip spring pieces are symmetrically arranged at the bottom of the packing ring. The strip spring pieces are in contact with and abut against the rubber sleeve. A rubber foot sleeve is provided at one end where the strip spring piece abuts against the rubber sleeve to increase friction.

[0011] Furthermore, the diameter of the packing ring is 6cm-10cm smaller than the top diameter of the oil mist discharge tank to ensure vibration space.

[0012] Furthermore, the strip spring is made of stainless steel.

[0013] Furthermore, the strip spring piece is arranged at the bottom of the packing ring by means of bolts.

[0014] Compared with the prior art, the present invention has the following advantages: Dynamic vibration oil cleaning: During the intake process, the oil funnel tank and the telescopic tube move simultaneously due to the unstable rate of oil and gas discharge. Through the linkage of the telescopic tube and spring 1, the strip springs on the packing ring contact the rubber sleeve on the telescopic tube, causing the packing ring to vibrate, prompting the oil droplets to quickly leave the packing surface. The vibration mechanism actively removes the oil accumulated on the packing ring to ensure the gas flow efficiency. Self-cleaning oil receiving structure: When the oil mist discharge tank stops taking in air, once the spring is fully extended, the oil receiving funnel tank will fit with the inner wall of the oil mist discharge tank and rise to scrape the oil from the tank wall of the oil mist discharge tank. In this process, the rising movement of the oil receiving funnel tank drives the friction and vibration of the strip springs and the rubber sleeve, thereby removing the excess oil droplets on the packing ring, which then flows out from the porous oil outlet plate. Once the spring is fully extended, it supports the telescopic tube and the oil receiving funnel tank, making it convenient for the staff to operate and rotate the rotating disk to rotate the oil receiving funnel tank. The strip springs can remove the oil remaining at the high position of the oil receiving funnel tank, and finally discharge it from the porous oil outlet plate. The oil receiving funnel tank fits with the inner wall of the tank body, directly collecting the oil droplets on the tank wall to avoid oil residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] In one embodiment, Figures 1 to 8As shown, an oil mist discharge separation device comprises a climbing platform 1 and an oil mist discharge tank 2. A notch 11 is arranged on the climbing platform 1 to facilitate manual operation of the climbing platform 1 to rotate the rotating disk 61. An exhaust pipe 21 is arranged on the top of the oil mist discharge tank 2 to discharge the filtered exhaust gas. An intake pipe 22 is arranged on the side of the oil mist discharge tank 2 to allow the oil and gas mixture to enter. A support leg 23 is arranged at the bottom of the oil mist discharge tank 2. The characteristics are as follows: an oil receiving funnel tank 3 is arranged inside the oil mist discharge tank 2, and a rubber ring 31 is sleeved on the oil receiving funnel tank 3 to receive the oil. The funnel tank 3 is used to receive the dripping oil drops, which flow out from the porous oil outlet plate 9. A telescopic tube 4 is arranged inside the oil receiving funnel tank 3, and a rubber sleeve 5 is arranged on the telescopic tube 4. The rubber sleeve 5 is provided with friction lines, and the rubber sleeve 5 has a certain friction ability. A porous oil outlet plate 9 is arranged between the bottom of the telescopic tube 4 and the oil receiving funnel tank 3 for discharging oil and slag. The oil receiving funnel tank 3 is fitted with the inner wall of the oil mist discharge tank 2, and the oil receiving funnel tank 3 moves with the telescopic tube 4. When no oil or gas enters, the spring 51 is fully extended to support the telescopic tube 4 and the oil receiving funnel tank 3, and the extension A spring 51 is sleeved on the telescopic tube 4 outside the oil receiving funnel tank 3, a limit plate 6 is set on the top of the telescopic tube 4, and the spring 51 is limited by the limit plate 6. A spring groove 7 is set on the top of the oil mist discharge tank 2, and the bottom of the spring 51 is limited by the spring groove 7. A rotating disk 61 is set on the top of the limit plate 6. The spring 51 is fully extended to support the telescopic tube 4 and the oil receiving funnel tank 3, which is convenient for the rotation of the rotating disk 61. A filter packing disk mechanism 8 is set inside the oil mist discharge tank 2. The filter packing disk mechanism has the function of oil and gas separation. The structure 8 vibrates when the telescopic tube 4 moves. Through the linkage between the telescopic tube 4 and the spring 51, the strip spring piece 83 on the packing ring contacts the rubber sleeve 5 on the telescopic tube 4, causing the packing ring 81 to vibrate, prompting the oil droplets to quickly break away from the packing surface, ensuring that the oil droplets can quickly drip from the filter packing plate mechanism 8 and that the gas can be discharged from the filter packing plate mechanism 8. The air inlet pipe 22 is arranged between the filter packing plate mechanism 8 and the oil receiving funnel tank 3, and can be located between the filter packing plate mechanism 8 and the oil receiving funnel tank 3 when the oil and gas are rushed in.

[0019] In one embodiment, see Figure 4 The filter packing disc mechanism 8 includes a packing ring 81, a spring 82 and a strip spring piece 83. The packing ring 81 is connected to the top of the oil mist discharge tank 2 through a group of springs 82. The telescopic tube 4 passes through the packing ring 81 and slides in the packing ring 81. A group of strip spring pieces 83 are symmetrically arranged at the bottom of the packing ring 81. The strip spring piece 83 contacts and abuts the rubber sleeve 5. A rubber foot sleeve 89 is provided at one end of the strip spring piece 83 abutting the rubber sleeve 5.

[0020] In one embodiment, see Figure 4 The diameter of the packing ring 81 is 6-10 cm smaller than the top diameter of the oil mist discharge tank 2.

[0021] In one embodiment, see Figure 4 The strip spring piece 83 is made of stainless steel.

[0022] In one embodiment, see Figure 4 The strip spring piece 83 is arranged at the bottom of the packing ring 81 through the bolt 84 .

[0023] In one embodiment, Figures 1 to 8 As shown, the oil and gas inlet state of production: the porous oil outlet plate 9 is connected to the external hose, and the oil and gas enter the oil mist discharge tank 2 from the air inlet pipe 22. As the oil and gas enter the oil mist discharge tank 2, the oil receiving funnel tank 3 moves downward to make room for the oil and gas. This movable setting enables the oil receiving funnel tank 3 to be used in scenes where the oil and gas pressure is unstable, effectively reducing the pressure exerted by the oil and gas on the oil mist discharge tank 2. The surface of the rubber sleeve 5 is provided with friction patterns and has friction ability. In the case of unstable oil and gas inlet, the telescopic tube 4 will telescope in the oil mist discharge tank 2. At this time, the strip spring 83 on the packing ring 81 contacts the rubber sleeve 5 on the telescopic tube 4, causing the packing ring 81 to vibrate. This vibration prompts the oil droplets to quickly detach from the packing surface, ensuring that the oil droplets can quickly drip from the packing ring 81, and at the same time, the gas can be discharged from the packing ring 81, thereby ensuring that the packing ring 81 has the ability to ventilate for a long time.

[0024] In one embodiment, Figures 1 to 8 As shown in the figure, the oil accumulation cleaning process: when the oil mist discharge tank 2 stops taking in air, the spring 1 51 will be fully extended to support the telescopic tube 4 and the oil receiving funnel tank 3. At the same time, the oil receiving funnel tank 3 will rise in contact with the inner wall of the oil mist discharge tank 2 to scrape the oil from the tank wall of the oil mist discharge tank 2. In this process, the rising movement of the oil receiving funnel tank 3 drives the strip spring piece 83 to vibrate with the rubber sleeve 5, thereby removing the excess oil droplets on the packing ring 81, and these oil droplets then flow out from the porous oil outlet plate 9. After that, the staff climbs onto the climbing platform 1 to operate the rotating disc 61 to rotate the oil receiving funnel tank 3, and the strip spring piece 83 can remove the oil remaining at the high position of the oil receiving funnel tank 3, and finally discharge it from the porous oil outlet plate 9.
